A vacuum producing suction and air blowing simultaneously at a same surface of the device, is disclosed here in. A pump and compressor work simultaneously to both blow and suck air through a dual-line hose. A pressure gradient is created between the surface of the device and a surface being cleaned, due to high pressure being created by the air blowing, and low pressure being created by the air sucking. This causes dust, dirt, and the like to be pulled from the surface being cleaned and sucked in a suction portal, and into a suction line of the dual-line hose. This can be accomplished with a central vacuum system or standalone vacuum.

A central vacuum cleaning system includes an inlet valve mounted at various locations in a structure or RV and connected to the inlet end of a vacuum conduit. A section of hose is slidably mounted within the conduit and extends from the inlet valve for cleaning an adjacent area. A pair of seals within the inlet valve retains a nozzle handle mounted on the end of the hose in a stored position when the hose is in a retracted position and provides an air seal between the handle and vacuum supply conduit. A locking mechanism mounted on one embodiment of the inlet valves automatically locks the hose in a selected extended position when manually pulled from the inlet valve by a locking finger engaging an adjacent section of the hose. An electric switch on the inlet valve enables a user to actuate the vacuum supply source. A mounting bracket enables the inlet valve to be mounted at various locations in the structure and a pair of seals enables the inlet valve to be open to the ambient atmosphere.

Vacuum cleaners to be mounted in a vehicle are disclosed. Some vacuum cleaners include a collector module configured to collect debris and a motor/impeller unit connected to the collector module. The collector module includes an air inlet and an air exhaust opening, and the motor/impeller unit is configured to draw air through the collector module from the air inlet to the exhaust opening. A hose storage module is connected to the air inlet, and a vacuum hose is stored inside the hose storage module.

A central vacuum cleaning system includes a locking collar mounted at various locations in a structure or RV and connected to the inlet end of a vacuum conduit. A section of hose is slidably mounted within the conduit and extends therefrom for cleaning an adjacent area. A pair of O-rings within the collar frictionally retains a handle mounted on the end of the hose in a stored position when the hose is in a retracted position and provides an air seal between the handle and vacuum supply conduit. A locking mechanism mounted on the collar automatically locks the hose in a selected extended position when manually pulled from the collar by a locking finger engaging an adjacent section of the hose. An electric switch on the collar enables a user to actuate the vacuum supply source. A mounting bracket enables the collar to be mounted at various locations in the structure and a ring formed on the collar enables the collar to be rotated to a desired position on the mounting bracket.

A vacuum cleaning system for a vehicle includes a debris collection unit, a fluid conduit connected to an outlet of the debris collection unit, and a vacuum suction unit fluidly connected to the debris collection unit by the fluid conduit. The debris collection unit defines a storage cavity for storing debris collected by the vacuum cleaning system, and is positionable in a first compartment of the vehicle. The vacuum suction unit is located remote from the debris collection unit, and is positionable in a second compartment of the vehicle separate from the first compartment

A vacuum hose has a switch that allows an operator to selectively send control signals to a transceiver to control the operation of a central vacuum unit. The switch may be located on a cuff or nozzle defining a distal end of the vacuum hose. The switch is not located on a head unit that couples to the cuff or nozzle and not located on a wall-mounted valve. The switch can be an energy harvesting switch that requires no batteries or no dedicated power source (i.e., not hardwired).
